How to Make a Video Overview in Gemini Notebook (formerly NotebookLM)

Audio Overviews made Gemini Notebook (formerly NotebookLM) famous, and the Video Overview is the visual sequel. It turns your sources into a narrated video that explains them. In fact, it comes in 3 formats, from 60-second Shorts to Cinematic films made with Veo 3, and you can check its plan before it renders. Which one should you make, and what will it cost your limits? Here’s the full walkthrough.

Key Takeaways

• Video Overviews come in 3 formats: Cinematic, Explainer and Short, which runs about 60 seconds (Gemini Notebook Help, 2026).
• Cinematic is English-only, 18+, and needs Pro, Ultra or an eligible Workspace plan.
• Turn on Review producer notes to check and correct the plan before the video renders.
• Generation can take more than 30 minutes.
• Pro and Ultra can turn off the visible watermark.

What are Gemini Notebook Video Overviews?

Video Overviews are narrated videos made from a notebook’s sources. Google says they turn hard material into “clear, digestible content” (Gemini Notebook Help, 2026). The AI host creates new visuals to illustrate points and pulls in “images, diagrams, quotes and numbers” from your documents (Google, 2025). You choose between 3 formats (Explainer, Cinematic and Short), and every format but Cinematic narrates in dozens of languages. Think of them as the visual sibling of the podcast-style Audio Overview. As a result, the controls will feel familiar if you know the audio version from our Gemini Notebook podcast guide.

How do you create a Video Overview in Gemini Notebook?

Select Video Overview in the Studio panel, or its pencil icon to customize first. Then pick a format, language, visual style and optional focus, and select Generate now. You need edit access to the notebook, and Google warns a video can take “sometimes, more than 30 minutes” (Gemini Notebook Help, 2026). Alternatively, skip the options and it uses the default settings. Here’s the full sequence:

1. Select the sources you want the video to cover.
2. Select the pencil icon on the Video Overview tile in Studio.
3. Choose a format: Cinematic, Explainer or Short.
4. Pick a narration language.
5. Choose a visual style, if you’re making an Explainer.
6. Add a steering prompt, or pick one of the suggested topics.
7. Turn on Review producer notes if you want to check the plan before it renders.
8. Select Generate now and carry on working, or Generate later to queue it if you’re out of usage.

In particular, the first two steps come straight from Google’s own instructions (Google, 2025). Importantly, the video builds in the background, so you can make other outputs or leave the page. When it’s ready, the player lets you change the speed from 1x, skip back or forward, and go full screen. Meanwhile, the mobile app can generate, play and download videos too, though Google says the app “may have limitations.”

How do you review the plan before a Video Overview renders?

Turn on Review producer notes, and Gemini Notebook drafts a plan for the video, which Google calls producer notes, that you can correct before anything renders. It works from the Studio panel or from the chat (Gemini Notebook Help, 2026). Here’s the flow:

1. Start it. In the Studio panel, customize the video and turn on Review producer notes before you select Generate now. Or ask in the chat, for example “Create a video summarizing [topic]”.
2. Steer it in the chat. Gemini Notebook suggests topics to include, based on your sources. Once you confirm them, cards in the chat let you guide the content, visual style and format, and a Review toggle sits there too (Google, 2026).
3. Wait for the producer notes. They can take several minutes, and you can keep working meanwhile.
4. Review them. In the Studio panel, select Review next to the finished producer notes and type all your feedback at once, such as “swap the order of the second and third scenes” or “open with a one-line summary”.
5. Select Proceed. The video renders from the corrected plan, which can take more than 30 minutes.

Why bother with the extra step? A video is the slowest output to redo. Rendering can run past half an hour, and Google’s help page describes no way to edit a finished video, unlike a Slide Deck’s Revise button. Reading the producer notes takes a few minutes, and a wrong emphasis or a scene in the wrong place is far cheaper to fix there. Proceed is final, though: once you select it, the producer notes can’t be refined. Two choices skip the step. Generate later schedules the video without producer notes, and the quick path (Video Overview, no toggle) renders straight away. Google’s announcement offers co-creation to all Gemini Notebook users, while its help page lists it for Google AI Ultra subscribers only. No Review toggle on your account? The quick path works the same either way.

Cinematic, Explainer or Short: which format fits?

Pick by audience and time. Explainer is the structured option, which Google says “connects the dots within your sources”. Cinematic is the immersive one, told through rich visuals and a story. Short covers the key ideas “in ~60 second videos” (Gemini Notebook Help, 2026). Language is the big split; specifically, Cinematic only speaks English. Similarly, the models differ. Cinematic videos use Gemini 3, Nano Banana Pro and Veo 3. Gemini acts as a creative director and makes “hundreds of structural and stylistic decisions” (Google, 2026). Notably, Cinematic is open to Google AI Pro and Ultra, 4 Workspace editions from Business Standard to Enterprise Plus, and 3 AI add-ons such as AI Pro for Education (Google Workspace Updates, 2026). In contrast, Shorts are portrait videos made with Nano Banana 2 Lite (9to5Google, 2026).

	Explainer	Cinematic	Short
Length	Not listed.	Not listed.	About 60 seconds.
Narration languages	80 listed.	English only.	73 listed, 80+ per Google’s blog.
Visual style choice	Yes, for 18+.	No.	No.
Who can make it	Everyone.	18+ on Pro, Ultra or eligible Workspace.	Everyone.
Best for	Learning a topic in depth.	A polished story to show others.	A quick recap to share.

Google’s help page carries two language lists, and when we compared them line by line, they don’t match. Explainer videos list 80 languages. The Short list has 73 entries, even though Google’s announcement says Shorts come “in more than 80 languages” (Google, 2026). The gaps run both ways. For instance, Konkani, Latin and Maithili appear only on the Explainer list, while Lao, Luxembourgish and Mongolian appear only on the Short list. Meanwhile, Google pitches Shorts for “complex formulas, diagrams, and scientific concepts,” so they suit quick study recaps. Thus, if you need a less common language, check the list before you spend part of your limit. Would you rather present slides yourself? See how to make slides in Gemini Notebook.

How accurate are Video Overviews?

Accurate enough for a first look, but polished visuals are not proof. Google’s own help page warns that the voices and visuals “may contain inaccuracies or audio glitches” (Gemini Notebook Help, 2026). Likewise, outside research points the same way. A 2026 test of 16 leading video models found they all scored about the same on how good the videos looked. Their scores for getting the science right, by contrast, varied widely. Its authors concluded that “advances in visual realism have not yet translated into reliable modeling of scientific and causal dynamics” (Zhang et al., arXiv, 2026). That matters most for the formats built on video models: Cinematic runs on Veo 3, and Shorts are pitched for formulas and diagrams. Therefore, check a few things before you share a video:

• Numbers and dates that appear on screen.
• Diagrams that redraw a figure from your sources.
• Any claim you plan to quote in class or at work.

How do you prompt and style a Video Overview?

The steering prompt sets focus and audience, and Explainer videos add 8 named visual styles. Google’s example of a focus prompt is “Focus only on the cost analysis sections of the business plan” (Google, 2025). If typing feels like work, pick one of the suggested topics instead. The styles are Classic, Whiteboard, Watercolor, Retro Print, Heritage, Paper-craft, Kawaii and Anime (Gemini Notebook Help, 2026). You can also let Gemini Notebook auto-select one, or choose Custom and describe your own look. However, styles are only for users 18 and over, and they don’t apply to Cinematic or Short videos. In addition, name the audience. For a beginner, Google suggests “I know nothing about this topic; help me understand the diagrams in the paper” as a prompt. In contrast, its expert example reads “I’m already an expert on X and my team works on Y; focus on Z” (Google, 2025). Need versions for 3 audiences? The Studio stores several videos in one notebook, so make one per role or language.

Rather steer from Claude or ChatGPT? Kortex MCP is included with Kortex Pro and Lifetime. With it, your assistant can start a Video Overview in any format and style from chat, with your prompt and sources attached. When we analyzed 776 Kortex MCP waitlist answers from September and October 2026, we found 91 people asking to make audio, slides or quizzes from chat. One asked to “generate template-based audio summaries, video summaries, written summaries, infographics.”

How do you download and share a Video Overview?

Select Download in the video player to save the file. You can also share it 2 other ways: a direct link or the whole notebook (Gemini Notebook Help, 2026). A link needs the notebook shared with the viewer, or open to “Anyone with a link” with full notebook access, and collaborators on a shared notebook find the video in their Studio panel. Public links are for consumer accounts only, since Google has switched them off for Workspace Enterprise and Education. In addition, only owners and editors can make a video public. Deleting a video breaks every link to it. Similarly, notebooks that use a Play Books ebook may block downloads. On a phone, open the video and tap More, then Download. Sending a recap to a class? Shorts were built for it, and Google says you can share them “with classmates or other people” (Google, 2026). Our Gemini Notebook for teachers guide has classroom ideas.

How to share a Gemini Notebook covers every sharing setting. Made one video per audience, across a few notebooks? Finding them all again is the next chore.

What is the Video Overview limit on each plan?

There’s no fixed daily number. Your allowance refreshes every 5 hours until you hit a weekly cap, and it weighs your prompt’s complexity, the models and features you use and the length of your chat. A bar under each Studio output shows how much of it the job will use (Gemini Notebook Help, 2026). Out of room? On the web, Generate later queues the video and, if notifications are on, tells you when it’s done, which can take a couple of hours. Notably, some users get a Video Overview made automatically when they first add sources, and Google says those don’t count toward limits. Our guide to Gemini Notebook usage limits explains the meter. Here’s how the plans compare:

Plan	Usage limit	Cinematic Video Overviews
Standard (free)	Standard limits.	Not included.
Plus	Two times standard.	Not included.
Pro	Four times standard.	Included, 18+.
Ultra	5x or 20x Pro.	Included, 18+.

Sources: usage limits page, Gemini Notebook Help (2026), and Google Workspace Updates (2026).

Google doesn’t publish a cost per video. Its limits do factor in the models and features you use, though, and a Cinematic video runs on three models at once: Gemini 3, Nano Banana Pro and Veo 3. So expect it to take a bigger bite out of your window than an Explainer. The bar under the Studio output shows how much bigger for your own notebook, so check it on both formats before you commit. The Plus, Pro and Ultra comparison shows what each tier adds.

Can you remove the video watermark?

Only on Pro and Ultra, and not everywhere. Google adds a visible watermark to the images and videos it makes. If you pay for AI Pro or Ultra, you can switch it off with the Visible watermarking toggle in the menu under your profile picture (Gemini Notebook Help, 2026). In India, South Korea and Vietnam, though, the visible mark always stays on, whatever your plan. Free and Plus plans, in contrast, can’t remove it at all. The invisible watermark, however, stays on every plan. Specifically, everything made with Veo, Omni or Nano Banana carries SynthID, a hidden digital mark that tags AI-made content. That covers all 3 formats: Cinematic uses Veo 3, Explainer styles use Nano Banana, and Shorts use Nano Banana 2 Lite. As a result, a video still reads as AI-made even with the visible mark off. Making a video for a public channel or a client? That alone can decide which plan you need. Our guide to removing the Gemini Notebook watermark covers what SynthID keeps and your options on free plans.

How does Kortex fit around Video Overviews?

A video is only as good as the notebook behind it. Kortex is a free Chrome extension that helps you fill and sort that notebook, and its users have run 105,000+ imports (Kortex, 2026). The Import button inside ChatGPT, Claude, Gemini and Perplexity sends a whole chat to a notebook, with prompts and replies labelled. In addition, Kortex Pro adds bulk import from pasted links, open tabs, a CSV or an RSS feed (Kortex pricing, 2026). Its Domain Router files links by URL, for example youtube.com links into a Watch Later notebook. Likewise, we built the prompt library for steering prompts that work, with folders, favorites and tags. Prefer to listen on a walk? Kortex can make audio from its Workspace. With Pro, it also publishes a private RSS podcast feed for Spotify, Apple Podcasts, Pocket Casts or Overcast. Video, audio or slides, each one starts from the same place: a notebook worth summarizing.

Frequently asked questions

How long is a Gemini Notebook Video Overview?

It depends on the format. Short Video Overviews run about 60 seconds, while the help center lists no set running time for Explainer or Cinematic videos. Making one takes longer than watching it: Google says generation can sometimes take more than 30 minutes, so you can keep working in the notebook meanwhile.

Can I download a Gemini Notebook Video Overview?

Yes. Open the video and select Download to save the file. There are 2 other ways to share it: a link, which works once the notebook is shared with the viewer or made public, or the whole notebook. Notebooks built on a Play Books ebook may not allow downloads.

Who can make Cinematic Video Overviews?

Users aged 18 or older on Google AI Pro or Ultra, Workspace Business Standard and Plus, Enterprise Standard and Plus, and 3 AI add-ons. They’re English-only. Google publishes no daily number for them: like other outputs, they draw on your compute-based usage limit.

What is the Gemini Notebook video limit?

There’s no fixed daily count. Video Overviews draw on a compute-based allowance that refreshes every 5 hours until a weekly cap, with two times the standard limits on Plus and four times on Pro. Out of room? Generate later on the web queues the video for you.

Do Gemini Notebook videos have a watermark?

Yes. Google adds a visible watermark to generated videos, which Pro and Ultra subscribers can turn off with the Visible watermarking toggle, except in 3 countries: India, South Korea and Vietnam. Every video made with Veo, Omni or Nano Banana also carries an invisible SynthID watermark, on every plan.

Are Gemini Notebook Video Overviews free?

Yes, apart from Cinematic. Explainer and Short videos work on the free plan, drawing on a compute-based allowance that refreshes every 5 hours until a weekly cap. Cinematic videos aren’t included on the free or Plus plans, since they need Pro, Ultra or an eligible Workspace plan.
